Marcos Galperin’s net worth is estimated at $5.2 billion as of November 2026, with a plausible range of $2 billion to $7 billion.

How much is Marcos Galperin worth in 2026?
We put Marcos Galperin at about $5.2 billion. MercadoLibre’s market value was $82.36 billion at a share price of $1,624.53 on 30 October 2026, according to a market data page. We assume he owns 7 percent.
Public estimates disagree because the stake is not stated plainly in the places most people look. A market data page puts insider ownership at 0.22 percent, which looks too low for a founder who holds shares through entities. Others assume a larger share and ignore the discount for selling a block of this size.
How Marcos Galperin built it
- Listed early. MercadoLibre went public on Nasdaq in August 2007, the first Latin American tech company to do so.
- Ran it as CEO for decades. He led MercadoLibre until Ariel Szarfsztejn took over on 1 January 2026, then became executive chairman.
- Backed other builders. He co-founded the Miami Sharks rugby team in 2023 and sat on Globant's board until 2020.

| Source | Our estimate | What it rests on |
|---|---|---|
| MercadoLibre stake, 7 percent | $5.77 billion | 7 percent of the $82.36 billion market value. The 7 percent is our assumption: we did not read a proxy ownership table. An SEC Form 4 from August 2024 does not mark him as a 10 percent owner, which is consistent with a stake below 10 percent. |
| Discount for a block this size | Minus $0.87 billion | 15 percent off. A holder of this size would sell over years, at a discount, and pay tax. |
| Other investments and family business | $0.30 billion | An assumption. He co-founded the rugby team Miami Sharks in 2023 and is a non-managing member of a Kaszek Ventures fund, which paid him a distribution of 35 shares in August 2024, per an SEC Form 4 filing. His family owned the leather maker SADESA. No amounts are published. |
The rows add to $5.2 billion. The first row carries 90 percent of the answer, and its main input is a guess. If the real stake is 4 percent the figure falls to about $3.1 billion, and at 9 percent it rises to about $6.6 billion by the same method.
What a point is worth
Our calculation: 1 percent of $82.36 billion is $823.6 million. The company has 50.7 million shares, so 1 percent is about 507,000 shares. At $1,624.53 each that is $823.6 million, the same answer. Revenue of $28.9 billion in 2025 (Wikipedia) puts the market value at 2.85 times sales.
Stepping aside
His Wikipedia page records that Ariel Szarfsztejn took over as chief executive on 1 January 2026 and Galperin became executive chairman. MercadoLibre listed on Nasdaq in August 2007, and eBay bought a 19.5 percent stake in September 2001 before selling out in 2016.
What would move the figure
The proxy table, once read, replaces our 7 percent. The share price matters more than any other input: a 10 percent fall in MercadoLibre cuts the estimate by about $0.49 billion. An announced share sale or gift would reduce it.
